About this thing called anger

As a Christian, it is hard to share faults, but actually as someone said, "We are not perfect, just forgiven". As I strive to draw closer to God to hear from Him, He is showing me things more clearly that I need to get rid of. I am an emotional person but emotions need to be expressed in the right way.
I realize that I have anger that is just under the surface. I am easy going and nice, maybe too nice, so that I don't let things that bother me out enough. Then they fester and sometimes come out in the wrong way.
I know that I shouldn't have anger, or that I should deal with it since it is an emotion, and let go of it. You need to deal with it, not just push it down. Anger, if not dealt with the right was, can lead to either depression, bitterness, or more serious things.
But how do you deal with it? The first thing is to find out what causes the anger.. Sometimes it takes some digging to get below the surface to find out the causes.
Many times we get angry because we feel we aren't getting what we deserve for what things we have done. We do good things and they aren’t appreciated. But the Bible says that "all our righteousness is as filthy rags". Whatever we do will never compare to what He has done for us and what He is doing through us. And He was put to death even though He did marvelous things. (That may be simplifying it but it is true.) And whether people recognize what we have done or not, it is God who sees.
The main thing is, why are we doing good deeds? It should be not to please men anyway, but to please God. And He is already pleased with us. As our Father He loves everything we do for Him or try to do for Him. Whether we give “a cup of cold water in His name” or risk our lives to save another’s life, it is all for Him. So what does it really matter if we get the recognition here from men? It is from God we need to hear, "Welcome home thou good and faithful servant."
Another reason we get angry is because of fear down under, fear that we won't get notice or we won't get something we want. Or fear that we will lose something. We may feel this “something” is natural and not something far out, like a million dollars, but rather, people in our lives, or to have money enough to survive. And when we do feel we have lost something or someone, we get angry. We think we will be miserable.
So, it is fear of loss underneath the anger. Fear also is not from God. It is not based on trust in God, that He will provide either people or things. It is not trusting that He has the best answer for us.
If we feel that we are losing things and people or life doesn't make sense, instead of getting angry at God, we/I should try to give the situations into His Hands and leave them there. We must look to the unseen rather than the seen, that His ways are higher than ours. Someday we will understand it all.
These are my thoughts at this time- I don't always follow what I believe. I don't always really trust God, but am trying. That's what it's about, trying, maybe failing and falling, but getting back up again. And lots and lots of prayer. and teaching and/or studying. With each trial, we grow closer to God and are a witness to others.
